Tech Note - RADIUS Troubleshooting Overview RADIUS Authentication, Authorisation and Accounting (AAA) is a core component of the amigopod platform and therefore being able to effectively troubleshoot any authentication issues between Access Controllers (RADIUS NAS devices) and the amigopod is essential. By default amigopod is configured to communicate RADIUS traffic on the following ports: o Authentication transaction on UDP port 1812 o Accounting transactions on UDP port 1813 o RFC 3576 transactions on UDP port 3799 The inbuilt firewall rules that protect the amigopod kernel are automatically provisioned to allow traffic to flow to and from these ports. Basic Configuration When configuring your network environment you must ensure that your Access Controller's RADIUS server definitions for both Authentication and Accounting are configured to match the above port settings. If your deployment demands that this default ports be changed from 1812 and 1813 these can be modified through the amigopod web interface under RADIUS Services Æ Server Configuration as shown in the screenshot below:
